GAS HOT WATER PRESSURE PROBLEMS

[hootowl]

We have a wall mounted gas hot water heater.We pump water from a rain water tank with a pump that cuts in and out depending on pressure. When the pump stops the water gets too hot to shower under.The constant pressure pump that a local plumber recommended is to expensive ($800).Possibly a tempering valve or a small quick recovery system might be needed. Something that won’t cost the earth.
If you have any advise I would sure appriciate it. Thanks

I’d suggest that you change your plumber if he’s quoting ypou that much.

Marinda. Get your plumber to check the RMC technical Manual or contact me on my email with regards to a pressure reduction valve set to slightly below the lower pressure switch setting, this will give you a constant pressure throughout the house and from the hot water system. this valve should be fitted to the incoming cold water to the building so that you have equal pressures to your shower.
alternativly check out a constant pressure system price yourself. The price of having a decent shower may end up to be similar anyhow.
